TO ALL WHOM IT MAY concerns:

Be it known that I, S. T. McDOUGAhL, of the city of Brooklyn, Kings countyfState of New York, have inventedan Improved Culinary-Apparatus; and I do hereby declare that theifollowing is a full,- clear, and exactdescription thereof,- reference being had to the accompanying drawing, which forms part of this specification.

My said invention has for its objectthe boiling and steaming of a number of difi'e'rent sorts ot' food ivith the same vessel, simultaneously, and with economyof time and fuel, with special reference to application to and use on gas and similar stoves, where'the flame is concentrated in a limited space. i To this end I constrnct a vessel, A, with several partitions, B, dividing the interior vertically into several compartments, each of which has an, opening at thetop to receive a steamer, e, made in the usualmanner.

The vessel A is generally made of the size ordinarily adapted to'the pot-hole of a stove; and the bottom,

instead of projectingdowmvard therein, with a single depression corresponding to the size of such hole, is

formed with several projections or depressions, at, corresponding to the number of compartments within the vessel A.

i The result is, that when used on a gas-stove, or the like, the flameoi' a central burner, though tending to concentrate at the centre of the vessel, and therefore in the midst of the projecting or depressed bottoms, will also envelope all such bottoms, causing the bulk of liquid within the vessel A to boil much 'sooncr than would be the case were the vessel not so divided.

Thus, by an economical arrangement of cooking-space, combinedwith a better distribution'of and increased heating-surface, an ordinary meal, composed, desired, of eight or more diflerent sorts of viands, may be ,PXT- pared in. less time and with less fuel than generally consnmed for one kind only, and the number of utensils required is reduced one-half.

I claim as my invention, and desire to secure by Letters Patent- As an article of manufacture, a boiler divided into several compartments by vertical partitions, and prof vided with a depression in the bottom of each compartment, in combination with as'tearu cooking vessel on one or each compartment, constructed and arranged in the manner and for the purpose herein described.
